T 0 all w 7mm it may concern:

Be it known that I, EDGAR H. BERRY, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Improvement in a Dispensing Device for Containers, of which the following is a specification.

This invention relates to a device in which the dispensing aperture may be opened or closed at will.

The object of my invention is the provision of a structure adapted to control the dispensing of even the most mobile and volatile liquids without requiring the use of removable parts, such as a cap or the like, and furthermore, to effect the closure of the device at the extreme outlet of the discharge passage, so that the latter will be securely sealed against the accidental entrance of foreign matter.

This invention is illustratedin the accompanying drawings, in which Figure 1 is an external plan view of the device.

Figure 2 is a vertical cross section on the line 22 of Fig. 1.

Figure 3 is an inverted plan view of the device.

Figure 4 is a partial section, correspond ing to Fig. 2, and illustrating a step in the assembling of the device.

Figure is a vertical cross section, identi cal with Fig. 2, excepting that the component parts are shown in a different position.

Similar letters refer to similar parts throughout the several views. 7

Referring to Figures 2 and 5, A is the top head of a container adapted to contain a dispensable liquid. The head A is provided with a neck A.

The neck A contains the cylindrical cup B, the connection between the two being permanent, and liquid-tight. Such a connection can be obtained by making the cup a force lit in the neck, and assembling the two pieces under heavy pressure.

The cup B has a flange B and a bottom B, the latter being pierced by the opening Z). The cup B carries a cylindrical shell cork C, which in turn carries the cylindrical neck D of the nozzle D.

The shell cork C fits snugly within the cup B and around the neck D to prevent Serial No. 171,699.

leakage, yet not so snugly as to prevent relative rotation of theseveral cylindrical parts. .The nozzle D has an axial aperture E, tapering to a small, conical, inwardly enlarging, discharge opening E at the extreme tip of the nozzle D. At the lower end of the aperture E, its Wall is provided with a female thread 6, adapted to engage as a nut, the helically coiled portion F of 'the plug F, which latter is formed from a single piece of cylindrical wire. This wire is'of suitable diameter, and its upper end F is of suitable form, to adapt it to plug the discharge opening E as indicated in Figure 5.

The plug F has an extension j, extending downward from the helically coiled portion F and adapted to engage 'a notch Z) which forms a part of the opening .7) in the bottom of the cup 13 as shown in Figure 3. The axial aperture E in the nozzle D is c0unterbored as shown ate, to provide a working clearance for the extension The nozzle Dhas a shoulderd, adapted to engage the upper surface of the cup flange B, and it is also provided with a projecting lip as shown at d Figure 4, which said lip is adapted to be spun or pressed into engagement with the lower surface of the cup flange B as indicated at d" F ignres 2 and 5. When the lip is spun or pressed as above described, care is taken to leavcthe engagement sufficiently loose to permit/of relative rotation'between the nozzle D and the'cup flange B.

After the several parts are assembled as above described, the nozzle D is free to rotate with reference tothe cup B, but the a plug F is restrained from such relative rotation, owing to the engagement of the extension 7 with the notch Z) in the cup bot tom B.

If the nozzle is nowrotated in the direc tion of the arrow.marked Close (Fig: l) the plug F restrained from rotating as above described,-is constrained to advance axiallyas a result of its. engagement with the female thread This travel can continue until the discharge opening'E in the nozzle D is closed by the plug F as shown in Fig. 5. The extension f is made long enough to enablevit to maintain its engagement with the notch b throughout this action.

By rotating the nozzle in the direction marked Open (F ig. 1) the reverse act-ion occurs, and this may be continued until the helically coiled portion F of the plug l5 seats against the cup bottom B as shown in Fig. 2. In this position the tip F of the plug F has been drawn back into the inwardly enlarging aperture E to provide an annular dispensing passage as indicated at G Fig. 2. This annular dispensing passage communicates freely with the interior of the container, whose contents can pass out through the opening I) of the cup bottom B, axially through the helically coiled portion F of the plug F, through the axial aperture E of the nozzle 1), and through the annular passage G to the final point of discharge E.
